ASH-PAN.

BPECIPICATION forming part of Letters Patent No. 336,934, dated March 2, 1886.

Application filed October 2, 1885. Serial No. 178,849. (No mo1lcl.)

To all whom it may concern.-

Be it known that I, J OHN H. MoKnowN, a citizen of the United States, residing at Barnesville, in the county of Belmont and State of 5 Ohio, have invented a new and useful Improvement in Ash-Pans, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in ash-pans; and the novelty consists in the construction, combination, arrangement, and adaptation ofthe'various parts forservice,substantially as hereinafter fully set forth, and

. specifically pointed out in the claim.

My improved ash-pan is particularly designed for use upon locomotives and other engines requiring an ash-pan. In locomotives it has been common to provide the ash-pans with openings on the sides to permit of the withdrawal of ashes therefrom,f0r which purpose it was necessary to stop the locomotive to enable the fireman to dismount, which stoppage is very objectionable, causing the loss of time and waste and consumption of fuel.

These holesoropenings alsoservedas air-ports to permit of the supply of air to the combustion-chamber of the furnace, but when the ash-pan has become filled with the fhot ashes the live coals therein fall out upon the track,

setting fire thereto in many instances, and causing the destruction thereof and adjacent property.

My invention has for its object to obviate these objections, and to provide means Whereby the ashes can be conveniently dumped from the pan while the engine is at rest or in motion; to provide for the regulation of air to the furnace; to provide for the reduction of the intense heat on the grate-bars arising 0 from the hot ashes in the pan by keeping said pan free therefrom, and to combine simplicity, strength, and durability of construction with thorough effectiveness and ease of operation.

In the accompanying drawings, Figure 1 is 5 a plan View of an ash-pan embodying my invention. Fig. 2 is a vertical longitudinal section thereof on the line a a; of Fig. 1, showing in dotted lines the position of the slats when it is desired to clear the pan of ashes.

Like letters of reference denote corresponding parts in both figures of the drawings, referring to which A designates an ash-pan of any ordinary or preferred construction, preferably rectangular in form, and B a series of slats arranged at the lower edge of the pan, extending transversely across the same, and forming the bottom thereof. Each slat extends transversely across the bottom of the pan, and at each end at the middle it has a journal pin or stud, c, which bears or rests in a bearing provided therefor in the ash-pan walls, or in the side walls of the ash-pan themselves. The transverse slats are thus pivoted centrally at each end, and are free to oscillate on their pivots to assumea vertical position, to allow of the egress of ashes from the pan and entrance of air thereto to supply the furnace to support combustion therein.

The transverse pivoted slats normally lie in almost a horizontal position, as indicated in full lines in Figs. 1 and 2, the outer edges thereof overlapping the edges of the adjacent slat or section, thus forming a bottom to the ash-pan,which is made up of centrally-pivoted 7 5 sections normally overlapping each other, to hold or retain the ashes in the pan, and which are capable -01 an oscillating movement on their pivots to permit the ashes to escape and air to enter the furnace to support combus- 8o tion,the quantity of such air admitted thereto through the sectional bottom of the pan being regulated by the distance intervening between the bottom sections, as will be very readily understood.

The sections are each provided with a downwardly-inclined stud or lug, d, at one edge thereof, near the middle, each lug of the sections being pivotally connected to an operating bar or rod, E, arranged beneath and ex- 0 tending centrally from end to end of the ashpan; and said rod E is pivoted-atits outer end to a bent arm,f, of an operating handle-lever,

F, which is pivoted or fulcr'umed upon a stud or lug, f, of the ash-pan.

The inclined downwardly-extending studs or lugs d and the longitudinally-movable rod or bar E are arranged exteriorly to-and beneath the body of the ash-pan,where they are out of the way and free from hinderance of the other parts of the device; and the inclined angular bent armf of the pivoted operatinglever F serves to lock the rod E and the centrally-pivoted sections or slats of the panbottom in position when they are closed, thus dispensing with an independent locking device.

The transverse ledge g at one end of the pan lies beneath the edge of the section that rests thereon, and the ledge k, that is arranged transversely of the opposite edge of said pan, is arranged above the edge of the section that bears against the ledge. These ledges serve to limit the movements of the sections or slats when they assume the approximately horizontal positions, to provide a closed bottom to the pan. The ledge g limits the downward movement of the edge of the section that rests thereon, and theledge h the upward movement of its section at the opposite end of the pan; and by reason of this peculiar construction and the edges of the section or sections intermediate between the end sections overlapping each other the movements of the sections, when they are operated to assume a horizontal position, are limited and stopped to provide close joints between the sections to out off the escape of the ashes and entrance of air to the fire-box.

The section at one end of the ash-pan rests at one edge upon atransverse strip, 9, secured to the inner wall of the pan, and at its rear edge it rests beneath the adjacent section, this arrangement being continued throughout the bottom, the front edge of one section overlapping or resting upon the rear edge of the preceding section,wl1ile the rear edge of the overlapping section rests or lies beneath the edge of the succeeding section until the last section is reached, the rear edge of which rests orlies beneath a strip, h, secured to the end wall of the ash-pan, as clearly shown; or, in lieu thereof, the position of the over and under lapping edges may be reversed, as will be very readily understood.

It is obvious that when the sections lie in approximately horizontal position,with their edges lapping each other, ashes from the furnace will fall thereon and be retained in the pan, and that by operating the lever they are caused to move or swing on their pivots and assume an inclined or vertical position, according to the adjustment of the handlelever, thus forcing the ashes from the pan by enabling them to descend through the spaces between the sectional bottom.

The sections can be operated to open or close the bottom when the train or locomotive is at rest or in motion, and the admission of air to the furnace through the ash-pan thereof can be regulated by opening the sections of the bottom to a greater or less degree.

The device is simple, strong, and durable in construction, and thoroughly effective and easy of operation, and can be manufactured at a slight increase in cost over ash-pans as or-.

dinarily constructed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improvementin ash-pans, the combination of the pan'body A, the centrally-pivoted sections or slats B, having the trunnions c at their ends, each of said sections lying in an inclined position and having their edges lapping the section before and behind it, and provided at one of its edges with the downwardly-extending inclined lug or stud d, the transverse ledges g and h, located at opposite ends of the pan and lying beneath and above the edges of the sections which rest thereon, and adapted to limit the movement of the sections and retain them in a closed position, the rod or bar E, located exteriorly to the pan and pivotally connected to the lugs cl, and a pivoted lever, F, having an angular inclined arm,f, pivoted at its free end to one end of the rod E, the whole combined and adapted to serve for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
